The right accessories for home baristas — what you actually need

Tamper, distributor, scale, knock box: what's essential, what's nice to have? We sort the accessory jungle. — by Dieter Eitz

Must-have accessories

Precision scale

Non-negotiable. Without a scale, no reproducible ratio is possible. Important: 0.1 g accuracy and a built-in timer.

Tamper (matching the portafilter)

The plastic tamper that comes with the machine is usually too small and too light. A stainless-steel tamper with the right diameter (58 mm) is the first sensible upgrade after the machine itself.

Knock box

Knocking the puck out on the edge of the sink damages the portafilter. A knock box with rubber padding is cheap and protects both your equipment and your furniture.

Useful accessories

Distributor

Coffee settles unevenly in the basket — channelling is the result. A distributor evens out the coffee bed before tamping.

Bottomless portafilter

The diagnostic tool for home baristas: lets you see whether the extraction runs evenly.

Starter kit recommendation: omaneo.GUDRUN + barista scale + 58 mm tamper + knock box + milk pitcher. That covers 90 % of the basics.

Nice to have

WDT tool: loosen the grounds before distributing
Milk thermometer: target 65 °C in the pitcher
Vacuum coffee canister: beans stay fresh 3 weeks longer
